i had some race rims made for mine and told the guys at ccw the hubs were 4.25 x 5 standard issue mustang/tbird units. they brought up the specs and made the centers. fit fine using acorn style lug nuts. my hubs are not milled btw and don't know why they would be, one car uses the jbl aluminum hat, the other uses a wilwood i believe, different rotor offset requires different caliper bracket and possibly some modifications to the rotor (chamfer cut on the inside edge), make sure everything fits. don't know why they would have to be hubcentric, could use the lug nuts to center the tire.

the fun has begun!
